TBH write amp was not considered, but since I've never heard of a write amp
over 1.5, for my purposes on the 256gb drives they still last welll over the

Again it does hurt a lot when your using smaller drives that less space
available for wear leveling.
I suppose
Hi,
I don't know if it's already been discussed here, but while
thinking about using the OCZ Vertex 2 Pro SSD (which according
to spec page has supercaps built in) as a shared slog and L2ARC
device it stroke me that this might not be a such a good idea.
Because this SSD is MLC based, write

The SSD design might implement wear leveling which moves an old block

Well pretty much by definition any writes shorten the drives life, the more
writes the shorter it is.
That said, here is some interesting math that I did before I built my first mlc
array.
